Hi Everett,
You sound busier now than when you were working. I know how the household changes when the kids move back in. Last year our daughter, her husband and 5 grandchildren (currently ages 12, 8, 5, 3 and 2) moved in with us. It impacts us all with this many people living here. It has increased my "honey do's" and decreased my Shopsmith time.
You should have editions 5 & 6 from me and Ron Dyck was going to send edition 4. With that you have editions 1 to 6 unless we find other editions in between any of them. I will get edition 7 to you soon. Below is the current list of Mark 5 manuals I know of from 1954 to the 1970's. I do know it is not complete. Anyone having a manual not on the list let us know here and I will add it. Also check the beginning of the thread on getting a copy to Everett. I will update the list below as we find additional manuals.

Newer editions of the manuals were mostly a result of changes to parts on the machine. Most of the setup and operation information, including the pictures, remained the same through the first Shopsmith Inc. manual. With the Magna Power Tool Corporation Manual Copyright 1957 Cat. No. EM 9100-B 4:57 the Parts lists and Drawings were no longer included in the manual but came separate. The manuals no longer required new editions because of part changes. With that change we need the separate parts lists too.
Edit on 10/09
I have been looking through the manuals I have and I believe there is at least one manual between editions 5 and 6 shown above. Manual Copyright 1955 5th Edition Cat. No. EM 9100-10:55* still shows the "A" headstock but is the first Magna PTC Manual. The next Manual I have identified is Copyright 1955 6th Edition Cat. No. EM 9100-A--10:56* with the "B" headstock but about a year after the headstock change in late October 1955. I cannot believe they would go that long without updating the drawings and parts lists. We should see something dated about 11-55 for the headstock change. I will adjust the list for this.
